Q.14/15 would like to inform the IETF
CCAMP Working Group and the Sub-IP Area Directors that Q.14/15 is beginning
work in defining the connection routing protocols for use in ASON networks, and
requests the benefit of the IETF's expertise in this area.

Q.12/15 has also developed an amendment
to ITU-T Recommendation G.8080 (Architecture for the Automatically Switched
Optical Network) to provide clarification on naming and structure of the
network for routing and signalling and add architectural support for discovery
procedures and protection/restoration.

A set of protocol-independent high level
routing architecture and requirements has already been specified in ITU-T
Recommendation G.7715 (see below) and Q. 14/15 has initiated work on a new
draft recommendation (numbered G.7715.1) describing the requirements for a
link-state method routing protocol for ASON.

Some of the following requirements have
been identified:

1.The routing protocol should
support partitioning of transport networks that may be controlled by using
multiple instances of different routing protocols at different levels.

2.The routing protocol should
support separation of control and data (i.e, transport) planes such that data
and control entities are not required to be co-located, and the scope of the
data plane resources seen by a routing function is not limited.

3.The routing protocol should
support distribution, abstraction and filtering of information within
hierarchical and partitioning relationships.

4.The routing protocol should
support independence of inter-domain and intra-domain routing protocols.

It should be noted that the scope of this
work is limited to routing of transport connections within ASON networks.

Q.12 and Q.14/15 wish to work
cooperatively with IETF in order to reach a common understanding of respective
terminology and available mechanisms.

An interim meeting of Q.14/15 will be
held on 9-13 June 2003, located in Chicago .The Rapporteur for Q.14/15 invites the
participation of interested IETF members in discussions of ASON routing
protocols at this meeting, and invites comments and input from IETF community
to progress this work.Those interested
in attending the interim meeting should contact the Rapporteur for Q.14/15 (H.
Kam Lam, hklam@lucent.com) by May 27, 2003.Any contributions directed to the meeting
must be submitted by June 2, 2003.
